Abstract: As a typical complex network structure of urban rail transit, it is of great significance to strengthen the management of important stations to ensure the connectivity and operational efficiency of the entire urban rail transit system. Based on the complex network theory, Space-P method was selected to build the topological structure model of rail transit network. The centrality of passenger flow and station property were added on the basis of three centrality indexes such as point degree centrality, closeness centrality and betweenness centrality, and the station importance ranking model of rail transit stations was constructed by variation coefficient method and VIKOR method. Then, taking Chongqing rail transit as an example, an empirical analysis was carried out, and the importance of 141 stations in the network was sorted and analyzed. The research results show that: Hongqihegou station is the most important station among 141 stations and in 8 lines.

摘要： 城市轨道交通是一种典型的复杂网络结构；加强重要站点的管理，对于保障整个城市的轨道交通系统连通性和运营效率有着重要意义。基于复杂网络理论，选取Space-P方法构建轨道交通网络拓扑结构模型，在点度中心性、接近中心性和介数中心性这3类中心性指标基础上增加了客流中心性和站点属性，并结合变异系数法和VIKOR方法构建了轨道交通站点的重要度排序模型；以重庆轨道交通为例进行了实证分析，对线网中的141个站点的重要度进行了排序分析。研究结果表明：红旗河沟是8条线路、141个站点中最重要的站点。
